This ntion ela es, t riinrerem in wringers and aims to provide aninexpensive const-ruction suitable for mass pro duction, lighter, andoccupying lessspace than wringers of the usual types.

The wringer of the invention comprises a frame constructed of metalstampings comprising vertical posts of channel form, which may eachcomprise a pair of channels, say of pressed steel, facing one another ateach side of the frame, and a horizontal top rail of inverted channelform bridging the posts and embraced at each end by a post or embracingat each end the upper end of a post, the rail being bolted or otherwisesecured to the posts.

Levers for applying pressure to the rollers may be in part accommodatedin the horizontal channel rail, being fulcrumed on pivot pinspenetrating the flanges of the rail.

Each post presents a guideway for springurged blocks presenting bearingsfor the roller journals.

In the accompanying drawings, which illustrate a wringer according tothe invention, Fig. 1 is a vertical section; Fig. 2 is a side elevation;Fig. 3 is an end elevation; Fig. 4 is a fragmentary detail view to alarger scale; Fig. 5 is a fragmentary section on the line 55 of Fig. 4;Fig. 6 is a detail View, partly in section, at right-angles to Fig. 4;Fig. 7 is a section on the line 77 of Fig. 2 to a larger scale; Figs. 8and 9 are detail views at rights angles to one another.

The wringer structure shown comprises two vertical end posts, eachconstituted by channel members 1 facing one another and connected bybolts 2 at their top ends to a horizontal rail 3 of inverted channelsection, the channel members 1 being notched at their top ends at 4 (seeFig. 6) to embrace and engage the ends of the rail 3, the upper cornersof the frame thus formed being reinforced by corner pieces 5 penetratedby the bolts 2.

Pressure levers 70f channel section are in part accommodated in the rail'3, being fulcrumed on pivot pins 8 penetrating the flanges of the rail3, washers 9 being interposed between the sides of the levers and theflanges.

The end posts serve as guides for bearing blocks 11 partly embracing thejournals 12 t he se a s-91hr 13 pa alle th h w ll rail 3. On top of theblocks 11 are plates 1 1 Which'bear the outer or remote ends of thelevers 7. Below the blocks 11 are blocks 15 presenting bearings for thejournals 16 of the lower roller 17, the blocks 15 abutting fixed plugs19.

Welded to the lower ends of the end posts are box members 18 (see Figs.5 and 6) to which are connected by bolts 21 cross-members which completethe rigid portion of the structure. 7

Projecting through a slot 22 in the Web of the rail 3 is a bolt 23having at its lower end a "I" head 24 engaging from below a slottedbuckle member 25 (see Figs. 8 and 9) the ends of which are located.below and engageable with pins 26 on the inner ends of the levers 7. Theshank of the bolt 23 is embraced by a helical spring 27 adapted to becompressed'between a handwheel 28 in a screwthreaded engagement with thebolt and a washer 29 hearing on the web of the rail 3. The arrangementis such that the bolt may be inserted from above the rail 3, the T- head24 being passed through the slots in the rail and in the buckle and thebolt thereafter axially rotated through 90.

We claim 1. In a wringer, in combination, vertical end posts formed asstampings of channel section, each post comprising a pair of channelsfacing one another, and notched at their top ends, a top rail formed asa stamping of inverted channel section bridging the posts and engaged bythe notched ends of the posts, box members welded to the lower ends ofsaid posts, cross members connecting said box members, rollers parallelwith the top rail having end journals, bearing members for said journalsaccommodated in the channels. presented by the posts, levers of channelsection pivoted to and accommodated within the top rail and having theirremote ends within the channels of the posts, and means applied to theadjacent, ends of the levers for exercising pressure on the rollers. v

2. In a wringer, in combination, vertical end posts formedas stampingsof channel section, each post comprising a pair of channels facing oneanother, and notched at their ends, a slotted top rail formed as astamping of inverted channel section bridging the posts and engaged bythe notched ends of the posts, box members welded to the lower ends ofsaid posts; cross members connecting said box members, rollers parallelwith the top rail having end journals, bearing members for said journalsaccommodated in the channels presented by the posts,'1evers of channelsection pivoted to and accommodated Within the top rail and having theirremote ends within the channels of the 1 posts, a slotted buckle beneaththe adjacent ends of the levers, and a member penetrating the slots inthe rail and in the buckle for applying upward pressure to the adjacentends of the levers.

In testimony whereof we have signedour 1 names to this specification.
